UNITE!) STAIRS HENRY L. FOUNTAIN, 0F BRYAN, TEXAS.

RAILWAY CATTLE-GUARD.

Application filed November 19, 1919.

To all lw w-m t may con cern Be it known that I, HENRY L. FOUNTAIN, a citizen of the `United States of America, and resident of Bryan, in the county of Brazos and State of Texas, have invented certain new and useful Improvements in Railway Cattle-Guards, of which the following is a specification.

rlll'iis invention relates to cattle guards for railway crossings and particularly to novel means whereby the guard is actuated to create or produce a barrier when an animal steps on a portion of the guard, there being novel means whereby the weight of the animal communicates motion to a barrier operating device to prevent the passage of the animal along the track.

A still further object of the invention is to produce novel means whereby the barrier is returned to its normal position when the weight is removed from the portion which is utilized to operate the said barrier.

A still further object of this invention is to produce a cattle guard of the character indicated whereby the operating parts thereof are shielded by the barrier so that they cannot be impaired by the entrance of snow or sand.

Vith the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in 'detail reference will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts in the several views and in which- Figure 1 illustrates a 1glan view of the cattle guard, embodying the invention.

Fig. 2 illustrates a section of the line l-l of Fig. l. A

Fig. 3 illustrates a perspective view of the cattle guard with the barrier lifted.

In these drawings A denotes a tiltable platform, portions of which are present on each side of the rails and between the said rails, and this platform A is attached to a member I which has a shaft J journaled in the sills L, constituting a portion of the frame.

An arm C is attached to the member I and it is oscillated as the member I rotates or partially rotates.

The barriers B are mounted on pivots Ii through the medium of the member H, it

being seen that the said member partially rotates when operated by the arm C, as will presently appear.

Normally, the barriers lie flat or horizontally, but are brought to the position shown in Fig. 3 when weight is applied to the platform A.

The sills or frame are assembled in operative position to cross ties M and N, and the relation of parts is such that the sections of the platform A may be forced down between the cross ties.

yIhe outer end of the arm C is preferably provided with an anti-frictional roller I), which latter is journaled in the bifurcated ends of the arm and a camming block E which extends from the inner face of a member B is engaged by the anti-friction rollei` to elevate the barrier when the arm is oscillated.

The member II is provided with springs F, which operate under pins G attached to the sills IJ, the said pins having their ends embedded or anchored in the sills.

The rails O are of the usual type and may be supported on bases P which rest on the sills.

R illustrates the side guards and they are provided with metal plates Q which serve to guide the hoofs of animals to the member A and prevent the animal from becoming entangled in the rails of the side guards.

From an inspection of the drawing and from the foregoing description it will be understood that the platform A when pressed down serves to elevate the outer end of the arm C, which in turn engages the camming member and communicates motion to the barrier and elevates it. When weight is removed the parts are automatically returned to their normal positions by use of the springs F, as stated, and the said springs will operate to lower the barrier and restore the other parts of the mechanism to normal position.

It will be noted that cattle can wallr over the guard in going out of the inclosure, that is, in going from the inside to the outside thereof.

I claim- 1. In a cattle guard, a sill, a member rotatably mounted in the sill, animal engaging device mounted on the said member, an arm projecting from the said member, barriers pivotally mounted in operative relation to the said arm, a member carried by the barrier engaged by the arm for operating the said barrier, and means for restoring the parts to normal position.

2. In a cattle guard, a sill, a rotatable member mounted with relation thereto, animal engaging' devices connected to the said member, a bifurcated arm projecting from the said member, an anti-friotion roller member rotatably mounted on the bifurcated end of the arm, barriers pivotally mounted l0 with relation to the sills, a eamming member attached to the barrier and engaged by the anti-friction roller for comi'nunicating` motion to the arm of the said barrier, and

means for restoring tne parts to normal 15 position.

HENRY L. FOUNTAIN.
